DH and I both have tiny families so Christmas Day this year is going to be at our house. DH's 80yo widowed Mum, my 80yo Mum and Dad who both have massive health issues, DH's brother and his wife plus us and our 2 children.
All fine. Except SIL has announced she will only come if my Mum isn't there.
Talk about playing silly buggers and upsetting everyone. In what world am I going to withdraw a Christmas invite to my parents? Why didn't she just make an excuse and decline the offer? Now we have hurt feelings, zero explanation from SIL, and a nasty atmosphere.
I'm really wishing she'd just said "Thanks, but no thanks" instead of playing stupid pick me games - AIBU?
